Great "outside the box" sort of idea
I think it would be great! Mind you there's the matter of making sure it doesn't turn this page into a sort of "Men's Health" or "Esquire" kind of ordeal, but physical fitness goes hand in hand with mental fitness in that a healthy mind has a hard time thriving in a not-so-healthy body. I run a mile and a half a day, 3-5 days a week (at about 8 MPH, start to finish), and do some body-weight oriented exercises in between, and I find that it helps keep me in a MUCH better frame of mind and helps me to map things out in my build projects and tech issues MUCH more effectively. I say give it a go, I'd be just as avid a fan of this as the rest of the OC3D page!
